The Postman (1997) (3/4)

In 2013, war has destroyed most of US, including the government. A solitary traveler is captured by a fascist military group called the Holnists led by Hitler-like General Bethlehem. When he escapes from the Holnists he finds an abandoned mail Jeep and uniform, and starts to travel through small cities, telling them he is a postman, a representative of the restored United States. Nobody believes him at first, but soon he has followers, and they start to prepare a revolt against Holnists.
